In turn, the host scheduler maps host threads to host cpus, so the mapping of vcpus to cpus depends on resource availability: if you have enough cpus, the scheduler will assign each vcpu to a separate cpu. The user will also be able to affect the mapping by binding vcpu threads to specific processors. -- Do not meddle in the internals of kernels, for they are subtle and quick to panic. ------------------------------------------------------------------------- Take Surveys.
